10844249 · 2020-11-24 ·

A stress tearable tape includes an elongated film and a hand tearing arrangement. The film has a non-adhesive surface and an opposed adhesive surface, and defines a longitudinal direction and a transverse direction. The hand tearing arrangement includes a plurality of pinholes formed along the longitudinal direction of the film. With the combination application of internal force, shear tension, compression tension, pinhole arrangement, and material's biaxial structure, and users' habit together, each of the pinholes enables the film being torn by hand with a force starting at one of the pinholes, such that the film is hand tearable at any section in the transverse direction thereof.

Perforating device for thermoplastic plates

The invention relates to a perforating device for thermoplastic plates, which relates to the technical field of a plate processing device. The device includes an electromagnetic chuck, one side of the electromagnetic chuck is connected with the driving member, the other side of the electromagnetic chuck is connected with a mounting plate and a spike. When the electromagnetic chuck is powered on, the spike is attracted below the mounting plate by an electromagnetic force generated by the electromagnetic chuck. A clamper is arranged below the mounting plate, the thermoplastic plate is fixed by the damper, and a heating system is also provided to heat the thermoplastic plate. As the electromagnetic chuck is powered on or off, the spike can be attracted in or separated from the mounting plate, respectively. Therefore, the perforating device can make a new plate be pierced during the cooling and curing process of the perforated plate.

Extrusion coated perforated nonwoven web and method for making
10821622 · 2020-11-03 · ·

A method for making an extrusion coated perforated nonwoven web. The method comprises the steps of extruding a molten polyethylene coating onto a nonwoven web, and aperturing the molten polyethylene coating through heat and pneumatic pressure differential to create microperforations therein at a density of between about 35 and about 120 perforations per linear inch. The resulting microperforated nonwoven web is then thermomechanically perforated by feeding it through perforating rolls, at least one of which has raised protuberances to create macroperforations that extend through at least the polyethylene coating. The macroperforations have a density of between about 6 and about 35 perforations per linear inch. The perforated nonwoven web is useful as a topsheet for absorbent articles.
